摘要：

Temperature-dependent magnetic measurements are reported for 4.34 nm antiferromagnetic Co3O4 nanoparticles mineralized in the Listeria innocua Dps protein cage. ac measurements show a superparamagnetic blocking temperature of roughly 5.4 K and give an extracted anisotropy energy density of (7.6 +/- 0.4)x10(4) J/m(3). The Neel temperature for the Co3O4 nanoparticles, determined with dc magnetometry, was determined to be roughly 15 +/- 2 K. (C) 2006 American Institute of Physics.
